الأسئلة الشائعة
What is glycerol (99.5%, spectrophotometric grade) primarily used for?
This high-purity glycerol is ideal for applications requiring optical clarity and low UV absorbance, such as spectrophotometry, chromatography, and analytical lab procedures.
What is the chemical formula and molecular weight of this glycerol?
The chemical formula is **C₃H₈O₃**, and the molecular weight is **92.05 g/mol**.
How should this glycerol be stored?
Store in a tightly sealed container at **ambient temperature**, away from strong oxidizers or contaminants.
What grade is this glycerol, and how does it differ from technical grades?
This is **spectrophotometric grade**, meaning it has ultra-low absorbance in the UV-Vis range, making it suitable for precise optical measurements—unlike technical grades, which may contain impurities.
Can Molekula supply this glycerol in bulk quantities?
Yes, we offer this product in bulk packaging (e.g., drums, IBCs) for large-scale applications—please contact us for specific volume requirements and lead times.
What documentation comes with an order of this glycerol?
Each order includes a **Certificate of Analysis (CoA)** confirming purity (99.5%+), spectrophotometric absorbance data, and compliance with spectrophotometric grade standards.
